When a LFS is dumping a mixed group of fish into a general tank you have no way to verify that they haven’t been cross breeding. This practice invariably leads to threads asking if the fish is a hybrid. RD is simply saying that based upon the traits of your fish and without knowing its history it is probably a hybrid. Which I think pretty much answered your question.
